Bootstrap Progress Meter

I recently discovered some progress meters on the w3schools.com website and wondered if I could leverage them in a StorLine project. The meters are part of a library of code called Bootstrap. I had no idea what bootstrap was, but I discovered on the site that "Bootstrap is the most popular HTML, CSS, and JavaScript framework for developing responsive, mobile-first web sites." Sounded like a good thing to leverage. Here is how I went about it:

  1. I located the code for several bootstrap meters here on the w3schools site. There are 2 parts to the code, the first goes in the head of your html document and the second creates the actual bar/meter. I copied both parts.
  2. In StoryLine (3 or 360) I added a trigger to fire at the 1st slide's timeline start that executes JavaScript. The script essentially adds the required html code to the header of the HTML5 player document then adds the code that creates the actual progress bar/meter directly in the StoryLine player.
    Here is the code:

    // Load required bootstrap references into a variable to facilitate appending the html player document.
    var appendHeader = '<meta name="viewport" content="width=device-width, initial-scale=1"><link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"><script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script><script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>';

    // Append the header with the code contained in the variable.
    $('head').append(appendHeader);

    // Load the required progress bar html code into a single variable.
    var progressBar = '<div class="progress" style="width:200px; position: absolute; margin: auto; right: 0; left: 0; top: 0px; bottom: 0px"><div class="progress-bar progress-bar-success progress-bar-striped active" id="my_progress" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="width:0%"></div></div>';

    // Add the code to the html player document after the title.
    $(".presentation-title").after(progressBar);

  3. Added 2 variables in SL: one to track progress as a number between 0 and 100 and another to track the color of the bar (red or green).
  4. For this demo, I added 2 buttons to modify both the variables in the prior step and to execute some code that uses these variables to modify/adjust the progress meter. Button one 1st adds 5 to the progress variable and then executes the following JS:

    // Establish StoryLine player connection and get current completion and current color of the bar
    var player=GetPlayer();
    var myProgress = player.GetVar("Progress");
    var barColor = player.GetVar("Color");

    // Check the color of the bar and change it to green if it is currently red.
    // Progress-bar-success is the green bar and progress-bar-danger is the red one.
    function toggleColor() {
         $("#my_progress").toggleClass("progress-bar-success");
         $("#my_progress").toggleClass("progress-bar-danger");
    };
    if (barColor == "Red"){
         toggleColor();
    };

    // Update the progress bar with the new value.
    $('.progress-bar').css('width', myProgress+'%').attr('aria-valuenow', myProgress);

    player.SetVar("Color", "Green");

    Button 2 is identical to button 1 except that it subtracts 5 from the progress variable and changes the meter to red if it is green. The code is identical to above except it replaces the word red with green and the word green with red.

Absolutely.
Replace this: $(".presentation-title").after(progressBar);
with this: $("div.controls-group").after(progressBar);

For some unknown reason, this breaks the color change so you also need to change the code on your buttons.
On BOTH buttons, replace this:
function toggleColor() {
     $("#my_progress").toggleClass("progress-bar-success");
     $("#my_progress").toggleClass("progress-bar-danger");
};
With this:
function toggleColor() {
     $("div.progress-bar").toggleClass("progress-bar-success");
     $("div.progress-bar").toggleClass("progress-bar-danger");
};

See attached SL3 file.

StoryLine 2 instructions to place this in the top of the player:

In step 2 of my original post...

  1. locate the following line of code
    $("div.controls-group").after(progressBar);
  2. and replace it with this one
    $("#timer_section").after(progressBar);

Everything else stays the same but please remember that this will only work in the HTML5 document, it does not work in the default Flash file.

The following will place the meter at the bottom of the page but ONLY if you are not using the built in slide progress meter.

I will have to try it again but I did not see a progress bar at the top of the screen. I just saw a percentage ie, 10%, 20% etc

just checked it on my iPhone and the top does not display. Is the progress bar in the player? If so, that might be why it is not showing on iPad or iPhone.

I have changed the absolute position of progress bar but it doesn't  effect.

Here is my code:

var progressBar = '<div class="progress" style="width:200px; position: absolute; margin: auto; right: 0; left: 0; top: 120px; bottom: 0px"><div class="progress-bar progress-bar-success progress-bar-striped active" id="my_progress" role="progressbar" aria-valuenow="0" aria-valuemin="0" aria-valuemax="100" style="width:0%"></div></div>';

This may be a Storyline newbie's crazy idea, if the code base being used can be pasted in a HTML page. 

And if that HTML page is called as small web object (scrolling locked)  in Master/all slides of the Storyline project  the progress bar could be placed in the stage area. 

Would that work you think Owen?  Maybe try it out Nitesh?

Hi All,

Firstly I want to give a massive thank you to Owen for finding this brilliant way to implement a working progress bar into the storyline player.

I've been working on customizing the look and feel of the original example Owen created and have managed to do the following:

1. Remove the need to have a 'Title' in the default storyline player - this can be achieved by replacing "$(".presentation-title").after(progressBar);" with "$(".top-tabs-left").after(progressBar);" - this will move the progress bar down to the 'Menu' bar.

2. With a little bit of help, I've managed to create the bar where any colour can be used rather than relying on the default settings - this will aid people who are trying to get the progress bar to fit into their own colour schemes.  See below:

var progressBar = '<div class="progress" style="height:15px; width:150px; position: absolute; margin: auto; right: 0; left: 0; top: 0px; bottom: 15px"><div class="progress-bar progress-bar-info" id="my_progress" role="progressbar" aria-valuenow="0" aria-valuenow="0" aria-valuemax="100" style="width:0%;margin:0 !important;background-color:#C9D140 !important;"></div></div>';

The bold section tells the css to ignore all previous colours and always use the colour indicated by the hex code.

3. Removing the blank white space around the progress bar.

var progressBar = '<div class="progress" style="height:15px; width:150px; position: absolute; margin: auto; right: 0; left: 0; top: 0px; bottom: 15px"><div class="progress-bar progress-bar-info" id="my_progress" role="progressbar" aria-valuenow="0" aria-valuenow="0" aria-valuemax="100" style="width:0%;margin:0 !important;background-color:#C9D140 !important;"></div></div>'; - 

Again just a simple bit of css that tells the code to ignore the previous information and replace with this.

4. Remove the colour change, this is personal preference I wasn't keen on the bar changing colour - nor was i keen on the bar dropping back down - I thought this might discourage users from clicking back if they thought they were going backwards. Simple change to the trigger - 

Adjust Variable 'Progress' = Assignment - Value = XX - When Timeline Starts - Object - Slide - On Condidtion that 'Progress' < less than XX. - If both XX match this will prevent the progress bar from rolling back.

5. Im currently working on (unsuccessfully) getting text onto the progress bar that is dynamically updated by the myProgress variable. However I've yet to find a solution that will not break the project from working correctly.

 

If you compare the original code vs mine, you will see I've made other changes such as the height of the bar etc..

 

If anyone does manage to get the text to dynamically appear on the progress bar please let us know! 

 

Thanks Guys - Hope this will help someone.

Is it possible? progress bar can come on stage area.

Hi Nitesh,

I just had a quick go at getting the progress bar on the slide itself, you can do this by changing

$("div.controls-group").after(progressBar);

to 

$(".main-window-slide-container").after(progressBar);

 

This will appear dead centre of the screen so you will need to amend the positioning to allow you to move it where you would like it but it's dead centre on mine. - Hope this helps.

Hi All,

After a little bit more work on this, I've managed to now get the player to display the variable as a text overlay on top of the progress bar.

This can be done by adding a new div to the variable 'progressBar' that is held within the Master Template. - See below:

var progressBar = '<div class="progress" style="height:21px; width:150px; position: absolute; margin: auto; right: 0; left: 0; top: 0px; bottom: 15px"><div class="progress-bar" id="my_progress" role="progressbar" aria-valuenow="0" aria-valuenow="0" aria-valuemax="100" style="width:0%;margin:0 !important;background-color:#C9D140 !important;"></div><div class="percentage" style="text-align:center; position: absolute; margin-left:43%; top:5px; font-weight:bold; color:#304EA0"></div></div>';

Within this div you can choose where to display your text, due to the size and width of mine I've opted for 43% left to centre the text. you can also style the text within this div, again changing the colour using a hex code.

The next thing to do so the text updates dynamically is to add the following:

//Add numerical value to the progress bar
$('.percentage').text(myProgress+'%');

This needs to be added to the JS trigger that is on each slide you are using to amend the variable 'Progress' in Storyline. - This will then take the div 'percentage' and fill it with the variable stored in 'myProgress' that was defined earlier on.

I've tested this on all the major browsers and it works loverly however due to the styling options chosen it looks a little odd on Firefox so the next task it to get that looking sharp on all browsers.

Hopefully this will aid someone either who has previously looked into this or at least coming into this fresh.

Again I've added an updated SL file with all the triggers required.
